To analyze differences in intensive care unit (ICU) utilization between a Canadian province and a U.S. area.
Retrospective data analysis of hospital discharge data and existing data from an international study of severity of illness in ICU patients.
Administrative data for the province of Alberta and the four counties of western Massachusetts for the years 1990 to 1991 were used.
Detailed data on consecutive ICU admissions from two Alberta hospitals, one western Massachusetts hospital, and 24 other U.S. hospitals for 3 months in 1991 were used.
ICU use and hospital mortality rates were compared for 50,030 hospital admissions divided into 11 patient groups.
ICU days per million population were two to three times as great in western Massachusetts as in Alberta.
The primary reason was higher ICU incidence (percent of hospitalized patients treated in the ICU) rather than a difference in hospital admission rate or length of ICU stay.
ICU incidence in western Massachusetts was significantly higher in ten of 11 patient groups-for the coronary bypass surgery group, there was no difference.
Western Massachusetts hospitalized patients are more likely to be treated in an ICU than are similar patients in Alberta.
There is no evidence that the greater ICU utilization in western Massachusetts led to a lower hospital mortality rate.
